Idaho Counties
There are44 Counties in Idaho.
Counties are the largest political divisions within the state.

When Idaho became a territory in March, 1863, there were four Counties in existence: Boise, Idaho, Nez Perce and Shoshone. By the time Idaho became a state 27 years later, there were 15 counties. The rest of the 44 Counties came into existence during the 30 years after Idaho became a state. Two of the former Counties disappeared during this time. Alturas, which was created in 1864, was later divided into the many Counties now found in central Idaho. Logan County was only in existence for six years, from 1889 to 1895. It was combined with Alturas to form Blaine County and Lincoln County, which was formed just two weeks after Logan lost its identity.

The history of our nation was a prolonged struggle to define the relative roles and powers of our governments: federal, state, and local. And the names given the counties, our most locally based jurisdictions, reflects the "characteristic features of this country!"
